摘要:
Mixed heliostat field combining, in the same field, heliostats of different sizes and/or with different types of facets, all of them having at least one facet and being canted or not, and either having spherical, cylindrical, flat or quasi-flat (spherical with a high curvature radius) facets, such that the solar field is optimised in order to minimise shadows and blockages between heliostats, as a result of correct positioning of the heliostats in the field.

Receiver with a configuration of saturated and superheated steam solar modules in a tower solar concentration power plant, in which said configuration allows the incidence of radiation on both sides of the superheated steam module, providing significant benefits for its durability and global control of the power plant.
摘要:
An economizer in a solar tower plant and operating method of said plant the purpose whereof is to make use of the heat from the heat losses generated around the solar tower receivers (3) to preheat the fluid with which the saturated steam or superheated steam solar receivers are fed. When the heat from the losses absorbed by the economizer (2) is not sufficient to achieve the necessary minimum temperature, a secondary economizer (4) is used which takes live steam (prior to it entering the turbine) and increases the temperature of the feed water of the receiver (3).
摘要:
Techniques, systems, apparatus and material are disclosed for regeneration or recycling of carbon dioxide into renewable liquid fuel. In one aspect, a method of recycling carbon to produce a renewable fuel can include harvesting carbon dioxide emitted from an industrial process. Biomass waste is dissociated under an anaerobic reaction to produce hydrogen. The harvested carbon dioxide is reacted with the biomass waste produced hydrogen under pressure and heat to generate a renewable fuel.

PCT No. PCT/AU97/00864 Sec. 371 Date Jun. 18, 1999 Sec. 102(e) Date Jun. 18, 1999 PCT Filed Dec. 19, 1997 PCT Pub. No. WO98/28579 PCT Pub. Date Jul. 2, 1998A solar energy collection system which includes n groups (13, 14) of arrayed reflectors (15) and n+1 target receiver systems (10, 11, 12) which represent absorbing surfaces to solar radiation that is reflected by the reflectors (15). The receiver systems (10, 11, 12) are elevated relative to the reflectors (15) and the reflectors are pivotally mounted to support structures (19) in a manner such that they may be positioned angularly to reflect incident radiation (I1, I2) toward one or the other of the receiver systems (10, 11, 12). The collector system is characterized in that a majority at least of the reflectors (15) within each group (13, 14) are arranged to be driven simultaneously to pivot through the same angle (+526 ), in that the reflectors (15) within each group (13, 14) are arrayed in two sub-groups (21 and 22), and in that a majority at least of the reflectors (15) within the respective sub-group (21 and 22) are oriented permanently toward respective ones of the receiver systems (10, 11, 12).
摘要:
A solar receiver (1, 1a, 1b) comprises an enclosure (2) delimiting a cavity (3) that is configured to receive a heat transfer fluid (4), at least one opening (5) in the enclosure (2) for access of solar radiation (R) into the cavity (3), at least one window (7) that seals the opening (5), and at least one cooling device (8, 8a, 8b) that is configured to cool the window (7). The cooling device (8, 8a, 8b) is configured to supply at least one window-cooling liquid fluid (9) to the window (7), such that the window-cooling liquid fluid (9) forms at least one liquid layer (10) on and/or in the window (7).
